So what could be causing the
Error: No nodes available for user’s profile’.
That problem seems due to a wrongly formatted key in the cfg file:
Error: Parse error at display option h264,mjpeg,clipboard.
Consider that no change is required in the configuration in order to get H.264 working. If you leave the defaults, H.264 will be automatically used when available.
Anyway, if I understand, you are now able to connect. So please send us a new set of logs when the session is running, as per instructions in my post above. We need client and server side logs.
